Abstract
Controlled environment studies were initiated to obtain chemical species and amounts of the essential oil content of Cinnamon, Italian Large Leaf, Osmin Purple, Red Rubin, and Sweet Dani basil grown hydroponically using the nutrient film technique (NFT). Seeds were sown in moist arcillite and transplanted into growth troughs (0.15 x 0.15 x 1.2 m) after 14-d in reach-in growth chambers, and nutrients continuously supplied by a half-Hoagland solution. Growth conditions included 300±25-μmol m-2 s-1 photosynthetic photon flux (PPF); 16/8 h light period, 25 ºC and RH of 70±10 %. Chemical composition of the components of essential oils was determined by GC/MS. Sixteen were found and 10 identified including 1, 8-cineole, linalool, neral, chavicol, geranial, and eugenol. Minor components included -terpineol, methyl chavicol, methyl eugenol, and γ-cadinene. Based on cluster analysis on six major components, the cultivars were classified into three chemotypes: “linalool and eugenol”, “neral and geranial”, and “linalool and chavicol”.
